摘要: Two Eu(III) complexes were synthesized using 4-acylpyrazolone ligands: 3-methyl-4-(4-methylbenzoyl)-1-phenyl-pyrazol-5-one (HPMMBP) and 3-methyl-1-phenyl-4-(4-phenylbenzoyl)-pyrazol-5-one (HPPMBP). The composition of the obtained solid was determined as Eu(PMMBP)3·C2H5OH Eu(PPMBP)3·3H2O based on elemental analysis further studied by IR, NMR TG-TSC data. lanthanoid complexation in state solution during liquid-liquid extraction (molecular diluent ionic liquid) is discussed.
